ABSTRACT

Embodiments of the disclosed technology are directed to devices, systems and/or methods for storing a substance in the base of a disposable container. Specifically, the disclosed technology is directed to an insert for use with disposable containers such as hot beverage cups. The insert may be wholly or partially formed of a container which is sealed enclosing a substance therein. The insert may be adapted to be detachably received into the base of common containers. In further embodiments, a system may employ the insert already having been nested into the base region of a provided beverage container. The substance enclosed in the insert may be, for example, an oral hygiene product such as mouthwash.

FIELD OF THE INVENTION

The present invention relates to disposable food and beverage containers, particularly to containers adapted to be received into another larger container used to store and/or consume food and beverages.

BACKGROUND OF THE INVENTION

Coffee, tea and other hot beverage are consumed by many on daily basis. The on-the-go nature of these beverages makes them a popular purchase for people en route to their jobs, schools, and other daily functions. As such, consumers typically purchase their morning brew after they have left their house and are already en route to wherever they have to be. The cater to these habits, coffee shops, stores, gas stations, and other vendors offer consumers to quick and convenient sales of coffee and other beverages in disposable, take away cups.

A well known side effect of coffee drinking is stained teeth and bad breath. The addition of sugar and other sweeteners to a morning beverage can also result in tooth decay and cavities. Because many consumers pick up their hot beverage on their way to work or school, they have already left their house and presumably brushed their teeth and have taken care of any other oral hygiene regiment. The consumption of coffee moments after may negate any oral cleaning or teeth whitening measures.

To address this problem, individuals may keep chewing gum or a toothbrush at their place of employment or education. However, given the ever increasing pace of peoples daily lives, the use of these products after having consumed a beverage could be easily foregone.

Mouthwash is a more convenient and quick way to address poor breath and teeth staining. Presumably, one would be more likely to gargle mouthwash from a bottle kept at that their office or school than to actually go through the motions of brushing their teeth. However, again, mouthwash kept at ones place of employment or education still requires the individual to consciously find their mouthwash bottle and perform the act of gargling.

Accordingly, it is desirable to provide a disposable, single-use container for storing a relatively small amount of liquid, such as mouthwash, in the base of a disposable cup.

SUMMARY OF THE INVENTION

Embodiments of the disclosed technology are directed to devices, systems and/or methods for storing a substance in the base of a disposable container. Specifically, the disclosed technology is directed to an insert for use with disposable containers such as hot beverage cups. The insert may be wholly or partially formed of a receptacle or smaller container which is sealed enclosing a substance therein. The insert may be adapted to be detachably received into the base of common containers. In further embodiments, a system may employ the insert already having been nested into the base region of a provided food and/or beverage container. The substance enclosed in the insert may be, but is not limited to, a food & beverage consumption related medium and/or an oral hygiene substance.

In an embodiment of the disclosed technology, a storage container is disclosed. The storage container may be used to store a liquid, solid, and/or any other substance in a specified quantity. The container may be formed of a first material defining a receptacle having a volume. “Volume”, for purposes of this specification, may be defined as the amount of space that a substance or object occupies, or that is enclosed within a container. The container may also have a generally planar bottom and a generally planar flange. The flange may surround the receptacle and may be generally parallel to the planar bottom. A sidewall or sidewalls may extend between the bottom and the planar flange.

The container may further employ a removable lid formed of a second material having greater flexibility than the first material. The lid may substantially cover the planar flange. An adhesive layer may be employed between the planar flange and the removable lid such that the removable lid is releasably adhered to the container, enclosing the volume therein.

The container itself may be adapted to be releasably nested into a hollow region disposed at a base portion of a larger, second container such that a portion of the planar flange contacts a portion of the hollow region. In embodiments of the disclosed technology, the second container may be a disposable cup. Furthermore, the volume of the storage container may store an oral hygiene substance. The oral hygiene substance may be toothpaste, mouthwash, mouthwash strips, gum, dental floss, dental floss wands, mints, Saline, Essential oils, cetyl pyridinium chloride (CPC), Chlorhexidine, Sodium hypochlorite and/or any other oral hygiene material known in the art.

In still further embodiments, the sidewall or sidewalls may be formed of four or more vertically disposed planar regions forming a polygon shaped cross section. That is, the cross section may be square, hexagonal or any other shape. Further the cross section may also be circular or irregular.

In another embodiment of the disclosed technology, a system is provided. The system may have a cup with a horizontally disposed bottom and a continuous side wall which terminates at a top end with an opening. The bottom may be disposed at a distance away from a lower extremity of the sidewall to form a hollow region.

The system may also employ a container formed of a first material defining a receptacle having a volume, a generally planar bottom, a generally planar flange, and a removable lid. The flange may surround the receptacle and may be generally parallel to the planar bottom. A container wall may extend between the bottom and the planar flange. The removable lid may be formed of a second material having greater flexibility than the first material. The lid may substantially cover the planar flange such that any contents within the container is releasably nested into the hollow region of the cup.

Still further, the disclosed system may include a substance enclosed in the container. The substance may be an oral hygiene substance. The oral hygiene substance may be toothpaste, mouthwash, mouthwash strips, gum, dental floss, dental floss wands, mints, Saline, Essential oils, cetyl pyridinium chloride (CPC), Chlorhexidine, Sodium hypochlorite and/or any other oral hygiene material known in the art. Alternatively, the substance may be a food & beverage consumption related medium such as condiments, seasoning, sauce, powders, tea leaves, vitamins, chewing gum, mints, gels, candies, nuts, sugar, salt, pepper, spices, instant beverage mix and/or any other substance that may be used injunction with the preparation and/or consumption of food and/or beverages.

In a further embodiment of the disclosed system, the container may be statically embedded in the hollow region using frictional contact between the flanges of the container and an interior surface of the of the hollow region. Still further, the system may employ an indentation disposed below the bottom of the cup in the hollow region. The indentation may conform substantially to an edge of the flange for detachably receiving the container within the hollow region. For purposes of this specification, “detachably” is defined as the ability of two or more components to be removed or separated with causing damage.

In still further embodiments of the disclosed system, the removable lid may have a tab extending therefrom. In embodiments, the tab may extend downwards past the container wall and may be folded to abut the planar bottom of the container. That is, the tab may be flush against the container bottom, but still accessible to a user such that pulling on the tab causes the container to be disengaged from the cup.

In another embodiment of the disclosed technology, a method is disclosed. The method is carried out, not necessarily in the following order, by: a) providing a liquid filled container, the container forming a receptacle defining a volume with a substantially planar bottom, wherein a removable lid encloses the liquid in the liquid filled container; b) pressing the liquid filled container into a base of a disposable beverage cup until the liquid filled container is statically nested in the base; c) using the disposable beverage cup for an intended purpose; d) detaching the liquid filled container from the disposable beverage cup; and/or e) opening the liquid filled container by at least partially removing the lid therefrom.

In further embodiments of the disclosed method, the step of pressing the liquid filled container into the base is carried out by snapping a side edge portion of the liquid filled container into a receiving indentation in the base of the cup. The receiving indentation may be disposed on the cup specifically with the disclosed liquid filled container in mind.

Alternatively, the indentation may be preexisting on presently available and future cups of the prior art. That is, some cups known in the art may already have a notch, raised lip, dot, adhesive, manufacturing feature and/or any other feature which may already be built into a disposable container. For example, if the liquid filled container is provided for sale in Store X, the liquid filled container may be specifically manufactured and adapted to fit in the base of disposable hot beverage cups already used and sold by Store X.

In another embodiment of the disclosed method, the step of pressing the liquid filled container into the base is carried out by frictionally engaging the side edge portion of the liquid filled container against an interior side wall the base of the cup.

In still a further embodiment of the disclosed method, the liquid filled container may be disposed below the bottom of the interior of the cup such that liquid in the cup does not contact the liquid filled container. That is, the liquid filled container is received into the hollow base region typically found at the bottom of disposable beverage cups. Most commonly, this feature is found on cups where a substantially portion of the cup is composed of paper, cardboard, card stock, and/or recycled paper.

The purpose of the folded pull tab 54 is two-fold in that it is initially used to detach the insert 40 from the cup 30. One removed, the pull tab 54 may be pulled upwards to pull the lid 50 away from the insert 40.

FIG. 13 shows a flow chart outlining steps taken in an exemplary method of the disclosed technology. The method may be carried out in any order, and some steps may be extraneous or moot under certain circumstances. In this embodiment, it is implied that a user would be using the insert on a preexisting cup. That is, in this embodiment of the disclosed technology, the cup may be any cup known in the art. The cup may be one purchased from a coffee shop or convenience store.

It is envisioned, in an embodiment of the disclosed technology, that a user grabs a disposable cup to fill with their daily hot beverage and also separately grabs an insert to embedded within the cup to be used at a later time. In alternative embodiments of the disclosed technology, the insert may be pre-inserted into the cup such that the entire assembled system is shipped and sold together.

Referring still to FIG. 13, step 100 involves a user being provided with an insert. The insert may have an oral hygiene product enclosed therein. The oral hygiene product may be, but is not limited to, mouthwash, mouth rinse, oral rinse, mouth bath, antiseptic, analgesic, anti-inflammatory, and/or anti-fungal. Conceivably the inserts would be available at a point of sale or near the beverage cups in a store, cafe or restaurant. The insert may be an “add-on” purchase to a hot beverage or the like.

Proceeding with the method, step 110 involves pressing the insert into the base of a cup, bottle or other container. In practice, it is envisioned that this step would occur prior to filling the container with food or beverage, but it conceivably may be performed while the container is full. In embodiments of the disclosed technology, the insert may be snapped or clicked into place. In other embodiments of the disclosed technology, the insert may be stuffed into the base and fixed by force of tension and/or friction.

The next step in the method, step 120, entails using the cup as intended. Such use may include filling the cup, refilling the cup, and/or consumption of the contents of the cup. Moving on to step 130, the insert may be detached from the cup upon consumption of the contents of the cup. The insert may be pulled out in manner consistent with the description pertaining to FIGS. 1 through 12. Detachment may involve pulling on a tab or simply gripping the body of the insert to remove it from its nesting place.

Proceeding with the method depicted by the flowchart in FIG. 13, step 140 may involve the user removing the lid from the insert. This step may be carried out in accordance with the description and practices described with respect to FIGS. 1 through 12. Once the lid is removed, the contents of the insert may be employed per their intended use. For example, mouthwash may be sipped from the insert and gargled by the user after consuming coffee.

In embodiments of the disclosed technology, the gargled mouthwash may be spit into the empty cup for later disposal. Finally, in step 150 the insert, cup and any remaining contents may be discarded. In further embodiments, one or more steps may be performed contemporaneously, in a different order, and/or skipped entirely.

One skilled in the art will recognize that an implementation of an actual apparatus or method may contain other components as well. While it is obvious that modification or proper change and combination can be made to the present oral hygiene insert according to the present invention by those skilled in the art, however, without departing from the contents, spirit and scope of the invention, any variations that are intended to achieve the techniques disclosed in the present invention should be within the scope of this invention.
